Therefore, GCD of numbers 21, 910, 236, 544 is 1

Given Input Data is 21, 910, 236, 544

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 21 is 3 x 7

Prime Factorization of 910 is 2 x 5 x 7 x 13

Prime Factorization of 236 is 2 x 2 x 59

Prime Factorization of 544 is 2 x 2 x 2 x 2 x 2 x 17

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(21, 910) = 2730

GCD(21, 910) = ( 21 x 910 ) / 2730

GCD(21, 910) = 19110 / 2730

GCD(21, 910) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 236

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(7, 236) = 1652

GCD(7, 236) = ( 7 x 236 ) / 1652

GCD(7, 236) = 1652 / 1652

GCD(7, 236) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 544

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

GCD(1, 544) = 544 / 544

GCD(1, 544) = 1

GCD of 21, 910, 236, 544 is 1
